-Parity-Ethereum 2.3.0-beta is a consensus-relevant security release that reverts Constantinople on the Ethereum network. Upgrading is mandatory for Ethereum, and strongly recommended for other networks.
+Parity 1.8.5 changes the default behavior of JSON-RPC CORS setting, detects same-key engine signers in Aura networks, and updates bootnodes for the Kovan and Foundation networks.
 
-- **Consensus** - Ethereum Network: Pull Constantinople protocol upgrade on Ethereum (#10189)
-  - Read more: [Security Alert: Ethereum Constantinople Postponement](https://blog.ethereum.org/2019/01/15/security-alert-ethereum-constantinople-postponement/)
-- **Networking** - All networks: Ping nodes from discovery (#10167)
-- **Wasm** - Kovan Network: Update pwasm-utils to 0.6.1 (#10134)
-
-Other notable changes:
-
-- Existing blocks in the database are now kept when restoring a Snapshot. (#8643)
-- Block and transaction propagation is improved significantly. (#9954)
-- The ERC-191 Signed Data Standard is now supported by `personal_sign191`. (#9701)
-- Add support for ERC-191/712 `eth_signTypedData` as a standard for machine-verifiable and human-readable typed data signing with Ethereum keys. (#9631)
-- Add support for ERC-1186 `eth_getProof` (#9001)
-- Add experimental RPCs flag to enable ERC-191, ERC-712, and ERC-1186 APIs via `--jsonrpc-experimental` (#9928)
-- Make `CALLCODE` to trace value to be the code address. (#9881)
-
-Configuration changes:
-
-- The EIP-98 transition is now disabled by default. If you previously had no `eip98transition` specified in your chain specification, you would enable this now manually on block `0x0`. (#9955)
-- Also, unknown fields in chain specs are now rejected. (#9972)
-- The Tendermint engine was removed from Parity Ethereum and is no longer available and maintained. (#9980)
-- Ropsten testnet data and keys moved from `test/` to `ropsten/` subdir. To reuse your old keys and data either copy or symlink them to the new location.  (#10123)
-- Strict empty steps validation (#10041)
-  - If you have a chain with`empty_steps` already running, some blocks most likely contain non-strict entries (unordered or duplicated empty steps). In this release `strict_empty_steps_transition` is enabled by default at block `0x0` for any chain with `empty_steps`.
-  - If your network uses `empty_steps` you **must** (A) plan a hard fork and change `strict_empty_steps_transition` to the desired fork block and (B) update the clients of the whole network to 2.2.7-stable / 2.3.0-beta. If for some reason you don't want to do this please set`strict_empty_steps_transition` to `0xfffffffff` to disable it.
-
-_Note:_ This release marks Parity 2.3 as _beta_. All versions of Parity 2.2 are now considered _stable_.
+Note: The default value of `--jsonrpc-cors` option has been altered to disallow (potentially malicious) websites from accessing the low-sensitivity RPCs (viewing exposed accounts, proposing transactions for signing). Currently domains need to be whitelisted manually. To bring back previous behaviour run with `--jsonrpc-cors all` or `--jsonrpc-cors http://example.com`.

+Parity 1.8.4 applies fixes for Proof-of-Authority networks and schedules the Kovan-Byzantium hard-fork.
+
+- The Kovan testnet will fork on block `5067000` at `Thu Dec 14 2017 05:40:03 UTC`.
+  - This enables Byzantium features on Kovan.
+  - This disables uncles on Kovan for stability reasons.
+- Proof-of-Authority networks are advised to set `maximumUncleCount` to 0 in a future `maximumUncleCountTransition` for stability reasons.
+  - See the [Kovan chain spec](https://github.com/paritytech/parity/blob/master/ethcore/res/ethereum/kovan.json) for an example.
+  - New PoA networks created with Parity will have this feature enabled by default.
+
+Furthermore, this release includes the ECIP-1039 Monetary policy rounding specification for Ethereum Classic, reduces the maximum Ethash-block timestamp drift to 15 seconds, and fixes various bugs for WASM and the RPC APIs.
+
+The full list of included changes:
+
+- Beta Backports and HF block update ([#7244](https://github.com/paritytech/parity/pull/7244))

+
+## Parity [v1.8.1](https://github.com/paritytech/parity/releases/tag/v1.8.1) (2017-10-20)
+
+Parity 1.8.1 fixes several bugs with token balances, tweaks snapshot-sync, improves the performance of nodes with huge amounts of accounts and changes the Trezor account derivation path.
+
+**Important Note**: The **Trezor** account derivation path was changed in this release ([#6815](https://github.com/paritytech/parity/pull/6815)) to always use the first account (`m/44'/60'/0'/0/0` instead of `m/44'/60'/0'/0`). This way we enable compatibility with other Ethereum wallets supporting Trezor hardware-wallets. However, **action is required** before upgrading, if you have funds on your Parity Trezor wallet. If you already upgraded to 1.8.1, please downgrade to 1.8.0 first to recover the funds with the following steps:
+
+1. Make sure you have 1.8.0-beta and your Trezor plugged in.
+2. Create a new standard Parity account. Make sure you have backups of the recovery phrase and don't forget the password.
+3. Move your funds from the Trezor hardware-wallet account to the freshly generated Parity account.
+4. Upgrade to 1.8.1-beta and plug in your Trezor.
+5. Move your funds from your Parity account to the new Trezor account.
+6. Keep using Parity as normal.
+
+If you don't want to downgrade or move your funds off your Trezor-device, you can also use the official Trezor application or other wallets allowing to select the derivation path to access the funds.
+
+The full list of included changes:
+
+- Add ECIP1017 to Morden config ([#6845](https://github.com/paritytech/parity/pull/6845))

+# Parity Dapps (JS-glue)
+
+Code generator to simplify creating a built-in Parity Dapp
+
+# How to create new builtin Dapp.
+1. Clone this repository.
+
+   ```bash
+   $ git clone https://github.com/paritytech/parity.git
+   ```
+
+1. Create a new directory for your Dapp. (`./myapp`)
+
+   ```bash
+   $ mkdir -p ./parity/dapps/myapp/src/web
+   ```
+
+1. Copy your frontend files to `./dapps/myapp/src/web` (bundled ones)
+
+   ```bash
+   $ cp -r ./myapp-src/* ./parity/dapps/myapp/src/web
+   ```
+
+1. Instead of creating `web3` in your app. Load (as the first script tag in `head`):
+
+   ```html
+   <script src="/parity-utils/inject.js"></script>
+   ```
+
+   The `inject.js` script will create global `web3` instance with proper provider that should be used by your dapp.
+
+1. Create `./parity/dapps/myapp/Cargo.toml` with you apps details. See example here: [parity-status Cargo.toml](https://github.com/paritytech/parity-ui/blob/master/status/Cargo.toml).
+
+   ```bash
+   $ git clone https://github.com/paritytech/parity-ui.git
+   $ cd ./parity-ui/
+   $ cp ./home/Cargo.toml ../parity/dapps/myapp/Cargo.toml
+   $ cp ./home/build.rs ../parity/dapps/myapp/build.rs
+   $ cp ./home/src/lib.rs ../parity/dapps/myapp/src/lib.rs
+   $ cp ./home/src/lib.rs.in ../parity/dapps/myapp/src/lib.rs.in
+   # And edit the details of your app
+   $ vim ../parity/dapps/myapp/Cargo.toml # Edit the details
+   $ vim ./parity/dapps/myapp/src/lib.rs.in # Edit the details
+   ```
+# How to include your Dapp into `Parity`?
+1. Edit `dapps/Cargo.toml` and add dependency to your application (it can be optional)
+
+   ```toml
+   # Use git repo and version
+   parity-dapps-myapp = { path="./myapp" }
+   ```
+
+1. Edit `dapps/src/apps.rs` and add your application to `all_pages` (if it's optional you need to specify two functions - see `parity-dapps-wallet` example)
+
+1. Compile parity.
+
+   ```bash
+   $ cargo build --release # While inside `parity`
+   ```
+
+1. Commit the results.
+
+   ```bash
+   $ git add myapp && git commit -am "My first Parity Dapp".
+   ```

-## Parity [v1.10.1](https://github.com/paritytech/parity/releases/tag/v1.10.1) (2018-04-17)
-
-Parity 1.10.1 is a bug-fix release to improve performance and stability. Among other changes, you can now use `--warp-barrier [BLOCK]` to specify a minimum block number to `--warp` to. This is useful in cases where clients restore to outdated snapshots far behind the latest chain head.

-## Parity [v1.10.0](https://github.com/paritytech/parity/releases/tag/v1.10.0) (2018-03-22)
-
-This is the Parity 1.10.0-beta release! Cool!
-
-### Disabling the Parity Wallet
-
-The **Parity Wallet (a.k.a. "UI") is now disabled by default**. We are preparing to split the wallet from the core client.
-
-To reactivate the parity wallet, you have to run Parity either with `parity --force-ui` (not recommended) or `parity ui` (deprecated) from the command line. Or, if you feel super fancy and want to test our pre-releases of the stand-alone electron wallet, head over to the [Parity-JS repositories and check the releases](https://github.com/Parity-JS/shell/releases).

-
-### Introducing the Wasm VM
-
-We are excited to announce support for **Wasm Smart Contracts on Kovan network**. The hard-fork to activate the Wasm-VM will take place on block `6_600_000`.
-
-To enable Wasm contracts on your custom network, just schedule a `wasmActivationTransition` at your favorite block number (e.g., `42`, `666`, or `0xbada55`). To hack your first Wasm smart contracts in Rust, have a look at the [Parity Wasm Tutorials](https://github.com/paritytech/pwasm-tutorial).

-
-### Empty step messages in PoA
-
-To **reduce blockchain bloat, proof-of-authority networks can now enable _empty step messages_ which replace empty blocks**. Each step message will be signed and broadcasted by the issuing authorities, and included and rewarded in the next non-empty block.
-
-To enable empty step messages, set the `emptyStepsTransition` to your favorite block number. You can also specify a maximum number of empty steps with `maximumEmptySteps` in your chain spec.
-
-### Other noteworthy changes
-
-We removed the old database migrations from 2016. In case you upgrade Parity from a really, really old version, you will have to reset your database manually first with `parity <options> db kill`.
-
-We fixed  DELEGATECALL `from` and `to` fields, see [#7166](https://github.com/paritytech/parity/issues/7166).
-
-We reduced the default USD per transaction value to 0.0001. Thanks, @MysticRyuujin!
-
-The Musicoin chain is now enabled with Byzantium features starting at block `2_222_222`.
